To all whom it may concern: 7

Be it knownthat I, Ancmn H. HOWELL a citizen of theUnited States, resident of Bearings;-and I declare the followingto be I Sacramento, in the county of Sacramento and State of California, have made a certain new. and. useful Invention in Axle-Shaft a full, clear, and exac't descriptionof the same, such as will enable others skilled'in the art to which itappertains-to make and use awa Fig. 2 is a detail central transverse section of the brake drum.

Fig. 3 is-a detail face view of the same.

Figs. i and 5 are detail sectional and face views of the anti-friction bearing.

Fig. 6 is a view similar to Fig. 1, showing a modification."

Fig. 7 is a detail sectional view of the brake drum and hub as in this modification,

' of the annular extension 17 of the tube 2,

and

Fig. 8 is a detail face view of the same.

The invention has relationto an attachment for motor cars and trucks of the Ford type,

having for an object to provide durable and eflicient means readily applicable, for relieving the rear axle shaft of the strain of the load which at present causes breakage of the axle shaft in cases of overload or unusual strain. Other objects and advantages will appear.

The inventionconsists in the novel constrnction-and combinations of parts, as hereinai'ter set forth.

in the accompanying drawings illustrating an embodiment of the invention, the numeral 2 designates the hub of a Ford car or truck; 3,-the rear axle shaft; 4, the rear axle housing, 5, the roller bearings; 6, the roller hearings sleeve, and 7 the roller bearings steel washer. I

At resent the strain of the load is transmitte through the rear axle housing to the roller bearings, and therefrom to the rear axle shaft, and causes breakage of the axle shaft as'stated.

To relieve this strain. and avoid this break age, applicantdiscardsrthe present rear axle brake drum, and substitutes therefor a rear axle brake drum 8, of the. same generail di Specification of Letters Patent.

mensio'ns as the discarded drum, and provided with a hollow cylindrical extension 9,

integral therewith gnd-concentric with the circumferential outer wall 10 of the drum.

Suitable anti-friction bearings are inter-' posed between the extension 9 and the rear PATENT orr es.

ing also rigid through frictidn'with the extension 9.

Asa result, the strain of the load is transmitted from the rear axle housing to the cylindrical extension 9, and to the brake drum with which said extension is integral, as well .as to the rear axle shaft.

The brake drum is provided with acentral aperture 16, of the proper diameter to have its circumferential marginal wall closely engage the outer circumferential wall whereby the strain of the load is transmitted from the brake drum to said hub, and to further transmit the strain of the load from the brake drum to the hub, the former is provided with a lateral recess 18, wherein fits the flange 19 of said hub, the circumferential edge of said flange closely engagin the circumferential wall of said recess. fie outer plate 20, loosely engaging the hub, the flange purpose of"relieving the rear axle shaft of the strain of the load, but it is found in practice that the said-bolts shear off, and an object of this invention is to prevent the shearing ofi of the bolts. I The extension 9 formed integrally with the brake drum is of special importance in preventing this shearing, and the lateral recess 18, engaged by the hub flange, is of assistance in preventing this shearing.

In Figs. 6,7 and 8 of the drawings a modification of the invention is shown, wherein the rear axle brake drum 8' and the hub 2' are formed integrally, or in one piece, the hollow cylindrical extension 9 of the brake drum being integral therewith, as in the preferred form f the invention. in this modification the other parts of the device are designated by the same reference numerals as in the preferred form, differentiated by the exponent 1.

The invention is readily applicable to any Ford car or truck at slight expense, and is found in practice to materially increase the mileage with a given expenditure of fuel, and to increase the loading capacity at least twice.

I claim:

1. Means for relieving the rear axle shaft of a motor vehicle of the strain of the load thereon, consisting of an axle shaft, 21- stationary housing therefor bearing the load,

anti-friction hearings between said housing and said shaft, a brake drum having a hollow cylindrical extension integral there with, and anti-friction hearings between said housing and said extension.

2. Means for relieving the rear axle shaft of a motor vehicle of the strain of the load thereon, consisting of an axle shaft, a stationary housing therefor hearing the load, anti-friction bearings between said housing and said shaft, a. brake drum having a hollow cylindrical extension integral therewith, an outer lateral recess and a central aperture, antip a. n.
